add to variable

sorry...

folks on my mud use Mush because it is free.
they want to figure percentages.
Trying to do this..

swings at you...(add one to swings variable)
you parry...(add one to parry variable)

..and eventually...

ttl swings...ttl parry...ttl percent of parries

and a way to clear both variables.

Thanx for any ideas,

Kura

For starters take a look at the help files for GetVariable("name") and SetVariable("name",value).

Also note that you'll get errors if you try and add a blank variable to a number, so your clear script should initialise them to 0 rather than simply blank them out.

All you need do to set the addition of a variable to 1 is:

SetVariable("VarName",(GetVariable("VarName") + 1))

Then to display, you could use the Note() and GetVariable() functions:

Note("Parry: " .. GetVariable("parryTotal"))
Note("Swing: " .. GetVariable("swingTotal"))

And for your percentage, if I'm guessing right, you will:

Note("Percentage parried: " .. ((GetVariable("parryTotal")/GetVariable("swingTotal"))*100) .. "%")

Clearing is probably the easiest thing, as you will:

SetVariable("varName","0")

Hope that helps!

Many many thanks..this worked great...here is what i got..

Thanks again!...:)
K.

p.s. is there any way to limit the percent thyng to just
3 numbers...i.e. ...

12.53333333
to 12.5

thanx again!

I would use the string.format function.



This should show the variable to 1 decimal place. Not sure if it is the best way to do it but it should work.

Garrion.

GetVariable returns a string, so you should convert the result to a number before you do the math...

In addition to string.format() you can also use math.floor() and math.ceil() which will round the number either up or down to the nearest integer.

Example in the help file is:

Note(math.floor(5.5))
-->5

Note(math.ceil(5.5))
-->6

But to get the decimal values, yes it is best to use string.format(). The help file on that will have a few examples which should explain all the options.

Also see commas.lua.



There is a "round" function in that which actually rounds (math.floor and math.ceil truncate up or down, whereas round goes up or down depending on which integer it is closer to).
